What You Need

To get started, you need a Simple Key kit and your original working key. The kit includes a user manual, an easy installer, a new key, and a key button pad. If you don’t have your original working key, this process won’t work.

  • Simple Key kit
  • Original working key

Compatibility

This guide covers specific Chrysler models:

  • Chrysler 300 (2008-2010)
  • Chrysler Town & Country (2008-2016)

Note that this method also works for some Dodge, Jeep, and Volkswagen models.

Initial Setup

First, open the Simple Key kit and inspect its contents. Ensure that the seal on the easy installer is intact and does not say “void.” If the seal is broken, return the kit for a new one.

Physical Key

The kit includes a physical key that you can cut at your convenience. While not necessary for the pairing process, it’s good to have it cut for emergencies.

Button Pad Replacement

If your current key doesn’t have specific buttons, you may need to replace the button pad. Here’s how:

  1. Open the key by pressing the switch and removing the internal key.
  2. Use a flathead screwdriver to open the key fob.
  3. Remove the circuit board and old keypad.
  4. Insert the new keypad and reassemble the key fob.

Activation

Now, let’s activate the new key fob. The activation code for Chrysler vehicles is “312.”

Entering the Activation Code

  1. Press the lock and panic buttons simultaneously until a blue light activates.
  2. Enter the code 312 by pressing lock, panic, and unlock buttons sequentially.
  3. Press lock and panic again to confirm the code.

If the light blinks rapidly, you made a mistake. Restart the process and try again.

Pairing the Key

Once the key is activated, you can pair it with your vehicle. Follow these steps:

  1. Locate the OBD port under the dashboard.
  2. Close all doors, ensure the vehicle is in park, and turn on the hazard lights.
  3. Set the dial position on the easy installer to “3.”
  4. Insert the original key and start the engine.
  5. Remove the seal from the easy installer and insert it into the OBD port.
  6. Wait for three beeps, then turn off the vehicle and remove the old key.
  7. Insert the new key and turn the ignition to the “on” position.
  8. Press the button on the easy installer and wait for three beeps.
  9. Turn off the engine, remove the key, and press the button on the easy installer again.
  10. Listen for a chime, indicating successful pairing.

Both the new and old keys should now work. You can program up to eight keys using the same easy installer.

Troubleshooting

If you encounter issues, refer to page nine of the user guide for customer service contact information. Here are some common errors and solutions:

  • If the easy installer beeps eight times, eight keys are already paired to your vehicle. Call customer service for assistance.
  • If the easy installer beeps at one-second intervals, it may already be paired to another vehicle. Obtain a new key.
  • If the existing key is not detected, ensure it is with you during the process.
  • If the dial position is incorrect, set it to “3” for Chrysler vehicles.
  • If the easy installer was unplugged during pairing, restart the process from the beginning.
  • If the vehicle won’t start with the new or old key, contact customer service.
